Description

Technical Field

[0001] This application belongs to the field of green building technology, and specifically relates to a method for generating a global carbon map based on multi-source data fusion. Background Technology

[0002] Carbon emissions are the foundation for governance and decision-making related to carbon emissions, such as the "dual carbon" strategic goals, which involve regulating energy consumption and carbon emissions management in the building sector, building carbon accounting, energy conservation assessment, carbon quota allocation, and achieving green buildings that are energy-efficient.

[0003] In related technologies, determining carbon emissions at the city level—that is, the total carbon emissions of the entire city—is coarse-grained and unsuitable for related governance and decision-making. How to improve the precision of carbon emission determination has become a technical problem that needs to be solved. Summary of the Invention

[0004] This application provides a method for generating a global carbon map based on multi-source data fusion, in order to solve the problem of how to improve the precision of the determined carbon emissions in related technologies.

[0005] This application provides a method for generating a global carbon map based on multi-source data fusion, the method comprising: Generate full-area carbon map data for the target area of ​​the target city. This full-area carbon map data includes: the carbon emissions from electricity of at least some individual buildings within the target area during the target accounting period. Specifically, the full-area carbon map data for the target area of ​​the target city includes: Obtain the electricity consumption of the target building object within the target area during the target accounting period, and determine the electricity carbon emissions of the target building object during the target accounting period based on the electricity consumption of the target building object during the target accounting period. The target building object is any building object within the target area. When the target building object includes a set of target individual buildings and all individual buildings in the target individual building set share a single electricity meter, the electricity carbon emission allocation weight of each individual building in the target individual building set is determined according to the electricity carbon emission allocation weight determination method corresponding to the building object type of the target building object. The electricity carbon emission allocation weight determination method corresponding to the building object type of the target building object is one of the following: electricity carbon emission allocation weight determination method based on load density, electricity carbon emission allocation weight determination method based on the number of households, or electricity carbon emission allocation weight determination method based on activity duration. Based on the electricity carbon emission of the target building object in the target accounting period and the electricity carbon emission allocation weight of each individual building, the electricity carbon emission of each individual building in the target accounting period is determined.

[0006] This application provides a computing device, including a processor and a memory, the memory being used to store a computer program; when the computer program is loaded by the processor, it causes the processor to execute the method provided in this application.

[0007] Beneficial effects: The method provided in this application can utilize multi-source data collected from urban areas to accurately map carbon data to individual buildings, obtaining comprehensive carbon map data. This comprehensive carbon map data can reflect fine-grained carbon emissions relative to city-level carbon emissions, i.e., the carbon emissions of individual buildings within the target area. This improves the precision of statistical carbon emissions. Fine-grained carbon emissions data can be used for related governance and decision-making, such as refined governance and decision-making under urban "dual carbon" objectives.

[0008] The method provided in this application takes into account typical situations where energy consumption data obtained from relevant entities is not reflected in the energy consumption of individual buildings. For example, the data provided by the relevant entities may represent the overall electricity consumption of a building object, such as an industrial park or a residential area. Alternatively, all electricity consumption may be mixed together, with the data identified by serial numbers, making it impossible to distinguish the energy consumption of individual buildings.

[0009] The method provided in this application allocates the carbon emissions of a target building object to the individual buildings within that target building object, obtaining the carbon emissions of each individual building in the target building object's set of individual buildings. Typically, this yields finer-grained carbon emission data, i.e., carbon emissions at the individual building level.

[0010] The method provided in this application allocates the carbon emissions of the target building object to the individual buildings of the target building object, ensuring that no carbon emissions generated by energy consumption that do not belong to the target building object are included in the calculation of the carbon emissions of the individual buildings in the target building object, thus obtaining a more accurate and fine-grained carbon emission amount, namely the carbon emission amount of the individual buildings.

[0011] The method provided in this application addresses the following issues: if carbon emissions of each individual building are collected one by one to obtain fine-grained carbon emissions, the cost of surveying each building individually, i.e., the cost of surveying the energy consumption of each individual building, is high, resulting in high cost, low efficiency, and difficulty in implementation at the regional scale.

[0012] The method provided in this application allocates the carbon emissions of the target building object to each individual building of the target building object, without having to investigate the energy consumption of each individual building, thus reducing the cost of obtaining fine-grained carbon emission data.

[0013] The method provided in this application takes into account the building object types of target building objects including a target single building set that shares a table, and uses a method for determining weights applicable to the corresponding situations to determine carbon emission allocation weights. As a result, more accurate allocation can be performed, and the corresponding carbon emission of each single building can be determined more accurately. Attached Figure Description

[0021] The method provided in this application includes: generating global carbon map data of a target area in a target city, wherein the global carbon map data includes: the carbon emissions of electricity from each individual building within the target area.

[0022] Generating full-area carbon map data for the target area of ​​the target city includes steps S101-S102.

[0023] Generate full-area carbon map data for the target area of ​​the target city. This full-area carbon map data includes: the carbon emissions from electricity of at least some individual buildings within the target area during the target accounting period. Specifically, the full-area carbon map data for the target area of ​​the target city includes: In step S101, the electricity consumption of the target building object within the target area during the target accounting period is obtained, and the electricity carbon emissions of the target building object during the target accounting period are determined based on the electricity consumption of the target building object during the target accounting period. The target building object is any building object within the target area. In step S102, when the target building object includes a set of target individual buildings and all individual buildings in the target individual building set share a single electricity meter, the electricity carbon emission allocation weight of each individual building in the target individual building set is determined according to the electricity carbon emission allocation weight determination method corresponding to the building object type of the target building object.

[0024] It should be noted that carbon emissions from electricity consumption can also be called carbon emissions from electricity consumption, and carbon emissions from electricity consumption can represent the amount of carbon emissions generated due to the consumption of electricity.

[0025] In this embodiment of the application, the target city can be any city to which the method provided in this embodiment of the application can be applied.

[0026] In this embodiment of the application, the target area can be any geographical area to which the method provided in this embodiment of the application can be applied.

[0027] As an example, the target area is a block within the target city.

[0028] As another example, the target area is a region within a target city that relevant personnel delineate based on their need to understand carbon emissions; the target area is a district within the target city.

[0029] In this embodiment of the application, the target building object within the target area can be any building object within the target area.

[0030] The target building may include a set of target individual buildings consisting of multiple individual buildings, such as a park, a residential area, or a sports complex. The target building may also be a single building, such as a residential building or an apartment building.

[0031] It should be noted that if the target building is a single building, determining the carbon emissions from electricity of the target building during the target accounting period will directly yield the carbon emissions from electricity of that single building during the target accounting period.

[0032] The method provided in this application is related to multi-source data of the target area. The multi-source data of the target area may include: point of interest (POI) data for each building object in the target area, energy and carbon basis data for each building object in the target area, and energy use association information for each building object in the target area.

[0033] In this embodiment of the application, multi-source data of the target city can be obtained, and multi-source data of the target area can be found from the multi-source data of the target city.

[0034] As an example, an AI agent can find multi-source data for a target region from multi-source data of a target city.

[0035] Multi-source data for the target city may include: built environment data, land use data, building data, map data, energy and carbon basis data, energy use information, and heating data.

Map data for the target city may include: Point of Interest (POI) data for buildings within the target city, national data on individual buildings, 2022 Digital Elevation Map (DEM) data, and national land survey data / remote sensing identification data. POI data for buildings may include at least some of the following: coordinates, function, and number of units within the building. The target city's basic energy and carbon data includes: electricity consumption data for buildings within the target city provided by the power grid company (building electricity consumption data); gas consumption data for buildings within the target city provided by the gas company (building gas consumption data); heating area data for buildings within the target city provided by the heating company (building heating capacity data); and benchmark data provided by relevant departments, such as carbon emission factor data. Energy use-related information for the target city includes: the number of electricity meters used by buildings within the target city; the number of gas meters used by buildings within the target city. Heating-related data for the target city includes: the coverage area of ​​heat sources used for grid heating within the target city; the location of heat exchange stations within the target city; boiler room registration data within the target city; the status of heat exchange stations within the target city; and the status of boiler rooms within the target city.

[0036] It should be noted that, in the embodiments of this application, the building object can also be called the responsible building object or the responsible subject.

[0037] For building object i, building object i may be an entity that includes a collection of individual buildings, such as a park, residential community, cultural and sports building project, or apartment project. Building object i may also be a single building. Building object i can be any single building object.

[0038] In this embodiment of the application, a single building can be a single building.

[0039] In this embodiment of the application, determining the multi-source data of the target area from the multi-source data of the target city may include: determining the building objects in the target area based on the boundary of the target area and the POI data of building objects in the target city; finding the POI data of the building objects in the target area from the POI data of all building objects in the target city; finding the energy carbon basis data of the building objects in the target area from the carbon basis dataset of the target city based on the name and location of the building objects in the target area; and finding the energy use association information of the building objects in the target area from the energy use association information of the target city.

[0040] In this embodiment of the application, the heating method corresponding to the target area can be determined. The heating method corresponding to the target area is grid heating and / or self-built boiler room heating.

[0041] In one possible implementation, if it is determined that at least one building object in the target area has building heating data including grid heating, then the heating method corresponding to the target area can be determined to include grid heating.

[0042] In one possible implementation, the heating method for the target area can be determined based on the heating-related data of the target city, specifically whether it includes grid heating. The heating-related data for the target city includes: the coverage area of ​​heat sources used for grid heating within the target city, the location of heat exchange stations within the target city, boiler room registration data for boiler rooms within the target city, the status of heat exchange stations within the target city, and the status of boiler rooms within the target city. Boiler room registration data includes: an identifier indicating whether the boiler room is self-built, and the unit to which the self-built boiler room belongs. The boiler room registration data for self-built boiler rooms also includes: the name of the building object to which the self-built boiler room provides heating. As an example, if the target area is within the coverage area of ​​heat sources used for grid heating within the target city, the heating method for the target area is determined to include grid heating. As another example, if the target area is within the coverage area of ​​heat sources used for grid heating within the target city and the target area is within the service area of ​​the corresponding heat exchange station, the heating method for the target area is determined to include grid heating. As another example, if the target area is within the coverage area of ​​the heat source used for grid heating in the target city and the target area is within the service area of ​​the corresponding heat exchange station and the corresponding heat exchange station is in operation, the heating method corresponding to the target area is determined to be: grid heating.

[0043] In one possible implementation, the heating method for the target area can be determined based on heating correlation data of the target city, specifically whether heating from self-built boiler rooms is included. For example, if the relevant units within the target area include self-built boiler rooms, then the heating method for the target area is determined to include heating from self-built boiler rooms. As another example, if the relevant units within the target area include self-built boiler rooms and the self-built boiler rooms are in operation, then the heating method for the target area is determined to include heating from self-built boiler rooms.

[0044] In one possible implementation, relevant personnel can conduct surveys within the target area to determine whether the corresponding heating method is grid heating and / or self-built boiler room heating. Once the heating method for the target area is determined, pre-stored survey results representing the corresponding heating method for the target area are retrieved.

[0045] In the embodiments of this application, the heating method corresponding to the target building object within the target area can be determined.

[0046] In one possible implementation, the heating method corresponding to the target building within the target area can be determined based on multi-source data of the target area. If the multi-source data of the target area contains building heating data for the target building, including data on heating from the main heating network, then the heating method corresponding to the target building includes main heating. If the multi-source data of the target area does not contain data indicating main heating for the target building, then the heating method corresponding to the target building does not include main heating. If the boiler room registration data of the corresponding self-built boiler room contains the name of the target building, then it can be determined that the corresponding self-built boiler room supplies heat to the target building, and the heating method corresponding to the target building includes heating from the self-built boiler room.

[0047] In one possible implementation, relevant personnel can conduct surveys within the target area to determine whether the heating method corresponding to the target building is a large-scale grid heating system and / or a self-built boiler room heating system. Once the heating method for the target building is determined, pre-stored survey results representing the corresponding heating method are retrieved.

[0048] In this embodiment of the application, in step S101, the electricity consumption of the target building object in the target area during the target accounting period is obtained, and the electricity carbon emissions of the target building object during the target accounting period are determined based on the electricity consumption of the target building object during the target accounting period.

[0049] It should be noted that, in the embodiments of this application, if the target building object includes a set of individual buildings, the set of individual buildings included in the target building object is called the target set of individual buildings.

[0050] In step S101, when the target building object includes a set of individual target buildings, the electricity consumption data of the target building object during the target accounting period can be retrieved from the multi-source data of the target area. This electricity consumption data can be the reading of a single meter (i.e., the master meter) shared by the target individual building set during the target accounting period. This electricity consumption data represents the electricity consumption of the target building object during the target accounting period, thus obtaining the electricity consumption of the target building object during the target accounting period. The reading can be called the meter reading. The electricity consumption data of the target building object during the target accounting period can indicate how much electricity the target building object used in total during the target accounting period.

[0051] In this embodiment of the application, the target accounting period can be one year.

[0052] In one possible implementation, the target accounting period is one year. In step S101, the following formula can be used to determine the carbon emissions of electricity generated by the target building during the target accounting period, based on the electricity consumption of the target building during the target accounting period: (1) in, This represents the carbon emissions from electricity generated by the target building during the target accounting period. This represents the annual electricity consumption (MWh) of the i-th meter installed within the target building object, i.e., the i-th meter among all the electricity meters used by the target building object. The annual average power supply emission factor of the power grid, for example The annual electricity consumption (MWh) reading of the i-th meter represents a portion of the electricity used by the target building object within a year, as recorded by the i-th meter.

[0053] It should be noted that, typically, industrial parks, residential communities, and sports-related buildings with multiple sports facilities use a single electricity meter. Therefore, for a target building group that uses a single electricity meter, when calculating the electricity consumption of the target building during the target accounting period using the formula, the value of i can only be 1 when summing.

[0054] In step S102, when the target building object includes a set of target individual buildings, the number of electricity meters used by the target building object can be found from the energy usage association information of the target building object.

[0055] If the target building uses only one electricity meter, it can be determined that all individual buildings in the target building group share one electricity meter.

[0056] In this context, the electricity meter shared by all individual buildings in the target single building cluster can be called the common electricity meter shared by all individual buildings in the target single building cluster.

[0057] In step S102, for individual building i in the target individual building set of the target building object, Determining the carbon emissions of a single building i during the target accounting period based on the carbon emissions of the target building object and the carbon emissions allocation weight of a single building i in the target single building cluster can include multiplying the carbon emissions allocation weight of the single building i by the carbon emissions of the target building object during the target accounting period to obtain the carbon emissions of the single building i during the target accounting period.

[0058] Wherein, individual building i can be any individual building in the target individual building set of the target building object.

[0059] In step S102, the following formula can be used to determine the carbon emissions of each individual building in the target accounting period based on the carbon emissions of the target building object during the target accounting period and the weights assigned to the carbon emissions of each individual building in the target building object's individual building set: (2) in, This represents the carbon emissions from electricity emitted by building i within the target building set of the target building object during the target accounting period. Building i can be any building within the target building set of the target building object. This represents the carbon emissions from electricity generated by the target building during the target accounting period. The carbon emissions from electricity generated by the target building during the target accounting period correspond to the meter reading (kWh) of the total electricity meter shared by all individual buildings in the target building cluster during the target accounting period. This represents the weighting of the carbon emissions from electricity generated by a single building i.

[0060] In this embodiment of the application, the method of determining the weight in step S102 can be called the weight allocation method. Step S102 is applicable to the scenario of one meter for multiple buildings, that is, one main electricity meter supplies electricity to multiple buildings or users.

[0061] In this embodiment of the application, multiple building object types can be pre-defined, and a method for determining the allocation weight of electricity carbon emissions corresponding to each building object type can be pre-defined. The method for determining the allocation weight of electricity carbon emissions for each of the multiple building object types can be one of the following: a method for determining the allocation weight of electricity carbon emissions based on load density, a method for determining the allocation weight of electricity carbon emissions based on the number of households, or a method for determining the allocation weight of electricity carbon emissions based on activity duration.

[0062] In one possible implementation, the target accounting period is one year, and step S102 includes: step S1021-step S1022.

[0063] In step S1021, when the method for determining the allocation weight of electricity carbon emissions corresponding to the building object type of the target building object is the method for determining the allocation weight of electricity carbon emissions based on load density, the annual electricity consumption per unit area of ​​each building type of each building in the target building object's target building set and the building area of ​​each building are obtained. In step S1022, the allocation weight of electricity carbon emissions for each individual building is determined based on the annual electricity consumption per unit area of ​​each building type and the building area of ​​each individual building.

[0064] For a given building type, the annual electricity consumption per unit area can be defined as the total amount of electricity consumed per unit area of ​​that building type within a year.

[0065] In one possible implementation, the target accounting period is one year, and step S1032 includes: step S10321.

[0066] In step S10321, the annual power consumption of the target single building is determined by multiplying the building area of ​​the target single building by the annual power consumption per unit area of ​​the building type of the target single building, wherein the target single building is any single building in the target single building set; the annual power consumption of the target single building is divided by the sum of the annual power consumption of the target single building set to obtain the power carbon emission allocation weight of the target single building, wherein the sum of the annual power consumption is the sum of the annual power consumption of all single buildings in the target single building set.

[0067] It should be noted that for a given building type, if the method for determining the carbon emission allocation weight for electricity is based on load density, the set of individual buildings included in this building type may contain different types of individual buildings. The load density-based method for determining the carbon emission allocation weight for electricity is suitable for determining the carbon emission allocation weight for each individual building in a set of individual buildings that includes different types of individual buildings. For example, building types such as industrial parks and residential communities all include different types of individual buildings, and the carbon emission allocation weight for these building types is determined using the load density-based method.

[0068] The load density-based method for determining the allocation weight of electricity carbon emissions is applicable to the use of a single meter for different types of buildings in parks and communities. Based on the annual electricity consumption per unit area of ​​different building types and the building area, the theoretical electricity consumption ratio of each building is calculated, and the carbon emissions of electricity consumption of each building are allocated according to this weight.

[0069] Dividing the annual electricity consumption of a single target building by the total annual electricity consumption of the set of target buildings yields the weighting of the target building's carbon emissions allocation, which can be expressed as follows: (3) in, This represents the weighting of electricity carbon emissions for building i within the target building set of the target building object. Building i can be any building in the target building set, i.e., the target building. This represents the building area of ​​building i. This represents the annual electricity consumption per unit area of ​​building type i. This represents the annual power consumption of a single building i. This represents the total annual power consumption of the target set of individual buildings, where the annual power consumption per unit area for each building type is standard data provided by the relevant department.

[0070] As an example, the annual electricity consumption per unit area for each building type adopts the "non-heating energy consumption index - electricity consumption" constraint value of the corresponding building type in Beijing's "Energy Consumption Standard for Civil Buildings" DB11 / T 1413-2023.

[0071] In one possible implementation, step S102 includes: steps S1023-S1024.

[0072] In step S1023, when the method for determining the carbon emission allocation weight of electricity corresponding to the building object type of the target building object is the method for determining the carbon emission allocation weight of electricity based on the number of households, the number of households or rooms in each individual building in the target individual building set of the target building object is determined. In step S1024, the allocation weight of electricity carbon emissions for each individual building is determined based on the number of resident units or rooms in each individual building.

[0073] Among them, the number of households can represent the number of apartments.

[0074] In one possible implementation, step S1024 includes step S10241.

[0075] In step S10241, the number of households or rooms in the target single building is divided by the total number of households or rooms in the target single building set to obtain the carbon emission allocation weight of the target single building. The target single building is any single building in the target single building set, the total number of households is the sum of the number of households in all single buildings in the target single building set, and the total number of rooms is the sum of the number of rooms in all single buildings in the target single building set.

[0076] It should be noted that, for the building object type corresponding to the method of determining the weight of electricity carbon emissions allocation based on the number of households, all individual buildings in the individual building set can be of the same type.

[0077] As an example, the method for determining the carbon emission allocation weights for electricity consumption for building types such as apartment buildings, residential buildings, and hotel buildings is based on the number of households. Apartment buildings, including sets of individual residential buildings, are classified as apartment complexes; residential buildings, including sets of individual apartment buildings, are classified as residential complexes; and hotel buildings, including sets of individual hotel guest rooms, are classified as hotels.

[0078] The method of determining the carbon emission allocation based on the number of households is applicable to multiple residential / apartment / hotel buildings sharing a single electricity meter, and the allocation is proportional to the total number of households in each building.

[0079] It should be noted that if the target building is a residential building, then in step S10241, the number of units in the target building is divided by the total number of units in the target building set. If the target building is a non-residential building, such as an apartment or hotel room building, then in step S10241, the number of rooms in the target building is divided by the total number of rooms in the target building set.

[0080] In this embodiment of the application, the weighting of the target individual building's electricity carbon emissions by dividing the number of units or rooms in the target individual building by the total number of units or rooms in the target individual building set can be expressed as follows: (4) in, This represents the weighting of the carbon emissions from electricity allocated to individual buildings within the target building set of the target building object. This represents the number of units or rooms in the target building, and U represents the total number of units or rooms in the target building set. The target building can be any building in the target building set.

[0081] In one possible implementation, step S102 includes: steps S1025-S1026.

[0082] In step S1025, when the method for determining the carbon emission allocation weight of the target building object is the method for determining the carbon emission allocation weight based on the activity duration, the effective running time of each individual building in the target individual building set of the target building object is determined in the target accounting time period. In step S1026, the carbon emission allocation weight of each individual building is determined based on the effective operating time of each individual building during the target accounting period.

[0083] In one possible implementation, step S1026 includes: step S10261.

[0084] In step S10261, the effective operating time of the target individual building in the target accounting time period is divided by the total effective operating time of the target individual building set in the target accounting time period to obtain the power carbon emission allocation weight of the target individual building. The target individual building is any individual building in the target individual building set, and the total effective operating time is the sum of the effective operating times of all individual buildings in the target individual building set in the target accounting time period.

[0085] It should be noted that all individual buildings of a building object type corresponding to the method of determining the weight of electricity carbon emissions based on activity duration can be of the same type.

[0086] As an example, the allocation weights for electricity carbon emissions for building object types such as cultural buildings and sports buildings are determined based on the duration of the activity. The building objects for the cultural building type are exhibition building complexes, and the building objects for the sports building type are sports building complexes. The target set of individual buildings for the cultural building type is multiple exhibition halls, and the target set of individual buildings for the sports building type is multiple stadiums.

[0087] The method of determining the weight of electricity carbon emissions based on the duration of the event is applicable to multiple buildings such as exhibition halls / gymnasiums with significantly different operating times sharing a single electricity meter, and the emissions are allocated proportionally based on the effective operating hours of each building.

[0088] The weight of a target individual building is obtained by dividing its effective runtime during the target calculation period by the total effective runtime of the target individual building set during the target calculation period. This weight can be expressed as follows: (5) in, This represents the weighting of the carbon emissions from electricity allocated to individual buildings within the target building set of the target building object. This indicates the effective runtime of the target individual building within the target calculation period. This represents the total effective runtime of the target individual building set within the target accounting time period.

[0089] The effective operating time of a target building within the target accounting period can be expressed as the average daily opening hours / days. As an example, the duration of the target building's daily opening hours is compared with... The product of the number of days a target building is open within the target accounting period is determined as the effective operating time of the target building during the target accounting period. As another example, the actual total opening time of a target building during the target accounting period is determined as its effective operating time during the target accounting period. Here, the actual total opening time of a target building during the target accounting period represents the total amount of time it was open during the target accounting period. The actual total opening time of a target building during the target accounting period can be reported by relevant personnel or determined through research by relevant personnel. Table 1 shows an example of a suitable method for determining carbon emission allocation weights for different building categories.

[0090] Table 1 In one possible implementation, step S101 is further included. Step S101 includes steps S1011-S1012.

[0091] In step S1011, when the target building is a single-function building using at least one electricity meter, the sum of the readings of all the electricity meters used by the target building during the target accounting period is determined as the electricity consumption of the target building during the target accounting period. In step S1012, when the target building is a multi-functional building using multiple sub-meters, the electricity consumption of each functional area in the target building, which corresponds one-to-one with the multiple sub-meters, is determined during the target accounting period. The electricity consumption of a functional area is the sum of the readings of all the meters used in the functional area during the target accounting period. The sum of the electricity consumption of each functional area during the target accounting period is determined as the electricity consumption of the target building during the target accounting period.

[0092] Step S1011 can be called the direct summation method. The direct summation method is applicable to single-function buildings with one meter per building or multiple meters per building. By directly reading or accumulating the readings of all the electricity meters directly associated with the building, the total electricity consumption of the building can be obtained, and the carbon emissions of the electricity consumption of a single-function building can be calculated.

[0093] Step S1012 can be called the itemized summarization method. This method is suitable for mixed-use buildings with multiple sub-meters (such as residential buildings with ground-floor commercial space), where a foundation needs to be laid for subsequent functional carbon accounting. The meters are assigned to corresponding functional zones based on their actual power supply range. First, the electricity consumption of each zone is calculated: the electricity consumption of each functional zone is the sum of all meter readings within that zone. Then, the total electricity consumption and carbon emissions of the mixed-use building are summed: the total electricity consumption of the building is the sum of the electricity consumption of all functional zones.

[0094] In one possible implementation, the global carbon map data further includes: the carbon emissions from natural gas of at least some individual buildings within the target area during the target accounting period; and generating the global carbon map data for the target city and its target area further includes step S103. Step S103 includes: steps S1031-S1032.

[0095] In step S1031, the gas consumption of the target building object during the target accounting period is obtained, and the gas carbon emissions of the target building object during the target accounting period are determined based on the gas consumption of the target building object during the target accounting period. In step S1032, when the target building object includes a target set of individual buildings and all individual buildings in the target set of individual buildings share a gas meter, the gas carbon emission allocation weight of each individual building in the target set of individual buildings is determined according to the gas carbon emission allocation weight determination method corresponding to the building object type of the target building object. Furthermore, the gas carbon emission of each individual building in the target accounting period is determined based on the gas carbon emission of the target building object in the target accounting period and the gas carbon emission allocation weight of each individual building.

[0096] Gas consumption refers to the amount of natural gas used. Carbon emissions from natural gas consumption can be called carbon emissions from natural gas consumption, and can be expressed as the amount of carbon emissions generated due to the consumption of natural gas.

[0097] In step S1032, for individual building i in the target individual building set of the target building object, Determining the carbon emissions of a single building i during the target accounting period based on the carbon emissions of the target building object and the carbon emissions allocation weight of the single building i in the target single building cluster can include multiplying the carbon emissions allocation weight of the single building i with the carbon emissions of the target building object during the target accounting period to obtain the carbon emissions of the single building i during the target accounting period.

[0098] Wherein, individual building i can be any individual building in the target individual building set of the target building object.

[0099] In one possible implementation, the target accounting period is one year. In step S1031, the carbon emissions of the target building during the target accounting period are determined using the following formula, based on the gas consumption of the target building during the target accounting period: (6) in, This indicates the carbon emissions from natural gas emitted by the target building during the target accounting period. This represents the annual gas consumption (m³) of the i-th gas meter installed within the target building (i.e., the i-th gas meter among all gas meters used by the target building). 3 The reading of ) The carbon dioxide emission factor of natural gas ( The annual gas consumption (m³) of the i-th gas meter in a year. 3 The reading represents a portion of the gas used by the target building object within a year, as recorded by the i-th gas meter.

[0100] It should be noted that, typically, industrial parks, residential communities, and sports-related buildings with multiple sports facilities use a single gas meter. Therefore, for a target building group that uses a single gas meter, when calculating the carbon emissions of the target building during the target accounting period using the formula, the value of i can only be 1 when summing.

[0101] In this embodiment of the application, multiple building object types can be pre-defined, and a method for determining the allocation weight of gas carbon emissions corresponding to each building object type can be pre-defined. The method for determining the allocation weight of gas carbon emissions for each of the multiple building object types can be one of the following: a method for determining the allocation weight of gas carbon emissions based on load density, a method for determining the allocation weight of gas carbon emissions based on the number of households, or a method for determining the allocation weight of gas carbon emissions based on activity duration.

[0102] It should be noted that when the target building object includes a set of target individual buildings and all individual buildings in the target individual building set share a single gas meter, the process of determining the carbon emissions of gas for each individual building in the target individual building set during the target accounting period is the same as the process of determining the carbon emissions of electricity for each individual building during the target accounting period when the target building object includes a set of target individual buildings and all individual buildings in the target individual building set share a single electricity meter.

[0103] In one possible implementation, determining the gas carbon emission allocation weight for each individual building in the target building set, based on the gas carbon emission allocation weight determination method corresponding to the building object type of the target building object, includes: when the gas carbon emission allocation weight determination method corresponding to the building object type of the target building object is a gas carbon emission allocation weight determination method based on load density, obtaining the annual gas consumption per unit area of ​​the building type of each individual building and the building area of ​​each individual building; and determining the gas carbon emission allocation weight for each individual building based on the annual gas consumption per unit area of ​​the building type of each individual building and the building area of ​​each individual building.

[0104] For a given building type, the annual gas consumption per unit area indicates the total amount of gas consumed per unit area of ​​that building type within a year. The unit area for each building type is based on standard data provided by the relevant authorities.

[0105] In one possible implementation, determining the carbon emission allocation weight for each individual building based on the annual gas consumption per unit area of ​​each building type and the building area of ​​each individual building includes: determining the annual gas consumption of the target individual building by multiplying the building area of ​​the target individual building by the annual gas consumption per unit area of ​​the target individual building type, wherein the target individual building is any individual building in the target individual building set; and obtaining the carbon emission allocation weight for the target individual building by dividing the annual gas consumption of the target individual building by the sum of the annual gas consumption of the target individual building set, wherein the sum of the annual gas consumption is the sum of the annual gas consumption of all individual buildings in the target individual building set.

[0106] In one possible implementation, determining the gas carbon emission allocation weight of each individual building in the target building set, based on the gas carbon emission allocation weight determination method corresponding to the building object type of the target building object, includes: when the gas carbon emission allocation weight determination method corresponding to the building object type of the target building object is a gas carbon emission allocation weight determination method based on the number of households, determining the number of households or rooms in each individual building; and determining the gas carbon emission allocation weight of each individual building based on the number of households or rooms in each individual building.

[0107] In one possible implementation, determining the carbon emission allocation weight for each individual building based on the number of units or rooms in each individual building includes: dividing the number of units or rooms in the target individual building by the total number of units or rooms in the target individual building set to obtain the carbon emission allocation weight for the target individual building, wherein the target individual building is any individual building in the target individual building set, the total number of units is the sum of the number of units in all individual buildings in the target individual building set, and the total number of rooms is the sum of the number of rooms in all individual buildings in the target individual building set.

[0108] In one possible implementation, determining the gas carbon emission allocation weight of each individual building in the target building set, based on the gas carbon emission allocation weight determination method corresponding to the building object type of the target building object, includes: when the gas carbon emission allocation weight determination method corresponding to the building object type of the target building object is a gas carbon emission allocation weight determination method based on activity duration, determining the effective operating time of each individual building in the target accounting period; and determining the gas carbon emission allocation weight of each individual building based on the effective operating time of each individual building in the target accounting period.

[0109] In one possible implementation, determining the carbon emission allocation weight of each individual building based on its effective operating time during the target accounting period includes: dividing the effective operating time of the target individual building during the target accounting period by the total effective operating time of the target individual building set during the target accounting period to obtain the carbon emission allocation weight of the target individual building, wherein the target individual building is any individual building in the target individual building set, and the total effective operating time is the sum of the effective operating times of all individual buildings in the target individual building set during the target accounting period.

[0110] In one possible implementation, the global carbon map data further includes: the thermal carbon emissions of at least some individual buildings within the target area during the target accounting period; and generating the global carbon map data for the target city's target area further includes: step S104. Step S104 includes: steps S1041-S1042.

[0111] In step S1041, the thermal carbon emissions of the target building object during the target accounting period are obtained; In step S1042, when the target building object includes a set of target individual buildings, the thermal carbon emission allocation weight of each individual building in the target individual building set is determined based on the heating area of ​​each individual building in the target individual building set, and the thermal carbon emission of each individual building in the target accounting period is determined based on the thermal carbon emission of the target building object in the target accounting period and the thermal carbon emission allocation weight of each individual building.

[0112] In step S1042, for individual building i in the target individual building set of the target building object, Determining the thermal carbon emissions of a single building i during the target accounting period based on the carbon emissions of the target building object and the thermal carbon emissions of a single building i in the target single building cluster can include multiplying the thermal carbon emissions of a single building i by the thermal carbon emissions of the target building object during the target accounting period to obtain the thermal carbon emissions of a single building i during the target accounting period.

[0113] Wherein, individual building i can be any individual building in the target individual building set of the target building object.

[0114] It should be noted that thermal carbon emissions can also be called thermal consumption carbon emissions. Thermal carbon emissions can represent the amount of carbon emissions generated due to the consumption of heat.

[0115] The target accounting period can be one year. The carbon emissions from the target area's grid heating during the target accounting period can be considered the target area's total grid heating carbon emissions for the entire year. The grid heating supply to buildings can be considered the heat supplied to buildings through the grid heating system for the entire year. Since heating is typically provided during the heating season, the target area's total grid heating carbon emissions for the entire year can be considered the target area's total grid heating carbon emissions for the entire year. The heat supplied to buildings through the grid heating system for the entire year can be considered the heat supplied to buildings through the grid heating system for the entire year. The carbon emissions from self-built boiler room heating in the target area for the entire year can be considered the target area's total self-built boiler room heating carbon emissions for the entire year. The carbon emissions from thermal energy in the target area for the entire year can be considered the target area's total thermal energy carbon emissions for the entire year.

[0116] The duration of the heating season can be called the heating period. For example, the heating period is 120 days.

[0117] In this embodiment of the application, if the heating method corresponding to the target area is grid heating, the carbon emissions of grid heating in the target area during the target accounting period can be calculated using the following formula, and the carbon emissions of grid heating in the target area during the target accounting period can be used as the thermal carbon emissions of the target area during the target accounting period: (7) in, This represents the carbon emissions from the large-scale heating network in the target area during the target accounting period, as shown in formula (7). This represents the carbon emission factor of the large-scale heating network. As an example, the carbon emission factor of the large-scale heating network can be expressed as a weighted average of regional heat sources (such as combined heat and power). Coal-fired boilers: As another example, the carbon emission factor for large-scale heating networks is the carbon dioxide emission factor for heat. This represents the heating supply of the large network for the k-th building object in the set of building objects j within the target area. This represents the regional network heat loss compensation coefficient, for example (value 1.08-1.15), which is a number within the range of 1.08-1.15. k is a variable, and the number of values ​​for k is the number of building objects in the building object set j.

[0118] In this embodiment of the application, if the heating method corresponding to the target area is self-built boiler room heating, the carbon emissions of the target area for self-built boiler room heating in the target accounting period can be calculated using the following formula, and the carbon emissions of the target area for self-built boiler room heating in the target accounting period can be used as the thermal carbon emissions of the target area in the target accounting period: (8) in, This represents the carbon emissions from self-built boiler room heating in the target area during the target accounting period, as shown in formula (8). The carbon dioxide emission factor representing thermal energy, as an example, is: , This indicates the heating area of ​​type i buildings within the target area (distinguishing between residential / office / commercial). This represents the heating load coefficient, and as an example, it takes the following values. Right now The value of is within the range One of the numbers is the heating load coefficient, which is adopted according to the Beijing local standard DB11 / T 1440—2017, for different building types. This represents the daily heating hours, for example, 24, which is the number of hours included in 24 hours. t represents the heating period, for example, 120 days. i is a variable, and the number of values ​​for i represents the number of building types related to the target area.

[0119] Daily heating hours can be used to indicate the number of hours of heating provided within a day.

[0120] As an example, the daily heating hours are 24, and the heating period is 120 days.

[0121] Class i is a type within a set of types, including residential, office, and commercial buildings. Class i represents building types relevant to the target area, and the heating area of ​​Class i buildings is the sum of the heating areas of all building types relevant to the target area. The heating area of ​​Class i buildings is also the sum of the heating areas of all building objects belonging to Class i within the target area's set j of building objects.

[0122] The value of q in the above formula is relative to... In this context, q is the heating load coefficient for building type i.

[0123] in, This represents the carbon emissions from self-built boiler room heating for building type i, which is relevant to the target area.

[0124] Heating area for building type i, which is related to the target area.

[0125] In this embodiment of the application, if the heating method corresponding to the target area is grid heating and self-built boiler room heating, the thermal carbon emissions of the target area during the target accounting period can be calculated using the following formula: (9) It should be noted that if the target area is the target block, then the thermal carbon emissions of the target area during the target accounting period are: the thermal carbon emissions of the target block during the target accounting period. If the target area is the area occupied by the target individual building set of the target building object, then the thermal carbon emissions of the target area during the target accounting period are: the thermal carbon emissions of the target building object during the target accounting period.

[0126] It should be noted that for a building object m in the set of building objects j within the target area, building object m may include a set of individual buildings, or it may be a single building. Relevant units provide the corresponding energy consumption data for building object m, such as electricity consumption, gas consumption, and building heating data including that provided by the main heating network. Here, building object m can be any building object in the set of building objects j.

[0127] The term "large network heating" can refer to the amount of heat supplied to a building through a large network heating system.

[0128] For a single building within the target area, if the single building belongs to the corresponding set of single buildings within the target area, then the single building is not considered a building object in the building object set j, but the set of single buildings to which the single building belongs is considered a building object in the building object set j.

[0129] For a single building within the target area, if the single building does not belong to any set of single buildings within the target area, the single building is treated as a building object in the set of building objects j.

[0130] For a given building type, if there is at least one building of that type within the target area, then that building type is considered a building type relevant to the target area.

[0131] In one possible implementation, the carbon emissions of electricity, gas, and heat of the target building object during the target accounting period can be added together to obtain the total carbon emissions of the target building object during the target accounting period.

[0133] In this embodiment of the application, after obtaining carbon map data, spatial carbon sink calculation can be performed: the carbon sink side identifies six types of carbon sinks, namely forest land, garden land, wetland, grassland, urban green space and rooftop greening, and performs carbon sink accounting according to the carbon sink coefficient method to obtain the carbon sink attributes of each carbon sink vector land boundary.

[0134] After obtaining spatial carbon sinks, net carbon accounting and full-area mapping can be performed. Net carbon accounting and full-area mapping include: combining carbon emissions and carbon sinks, using a "dual-map" algorithm to calculate net carbon, and generating a 3D carbon map based on a GIS platform, achieving visualization at three spatial scales: "city-block-community". The "source-sink" situation can be displayed on a single map, namely the 3D carbon map.
